Yay, another atmosphere mob. Seriously, we need more things like these. So far we have: Squids, Bats, Polar Bears and Parrots and to an extent ocelots, wolves, rabbits and llamas.
My biggest complaint about the wild life mobs is that most of them are persistent like farm animals. Squids, ocelots and bats are the only ones that aren't persistent. Polar bears, wolves, rabbits, llamas and parrots (if they are persistent) should use the "old" method of spawning in which they spawn and despawn. That way they seem more wild (and refill the mostly lifeless void after players have slaughtered everything in the area). Things that can be tamed would become persistent when tamed like they are now. Non-persistent wild life also means hunting becomes and aspect of the game which in my opinion is cool.
in the snapshot video made by Xisumavoid it seems that parrots spawn without filling a mob cap. They also don't despawn though, so the world gts kinda flooded with parrots at the moment. But they could still go the not persistent way, which I would love to see.

Since we don't really know anything about those parrots, apart from what they look like, who knows.
Maybe they do the Mo'Creatures bird thing, where you can carry them on your head, and they will cause you to glide instead of fall like a chicken would. That would be a pretty neat new mechanic.
